Yes. Pain in the back can affect a leg muscle.
This is named 'referred pain'.
It is wise to see a medical doctor when pain such as this lasts more than a 24 hours.
yeah
Some cells have a greatly, or even completely, deminished ability to reproduce once they become specialized. Muscle and nerve cells are a prime example of this.
The short answer is "concentrated lactic acid." Concentrated lactic acid can get trapped in the spindle in the muscle fiber and can not get out. When this lactic acid gets trapped in the muscle spindle the feedback nerves that are protected in the muscle spindle can only send a weak signal to the cerebellum. A weak signal from the feedback nerve to the cerebellum tells the cerebellum to contract a muscle. The feedback nerve is trying to send a strong signal which would tell the cerebellum to relax but because the concentrated lactic acid is trapped in the spindle and interfering with the feedback nerve the correct signal can not get to the brain. As a result the muscle keeps contracting and it never relaxes. The muscles gets stuck in this "bad signal loop" which causes many other problems in the body.
To study the physiology of nerve fibers, you would need to isolate a specific muscle and the nerve innervating that muscle. This allows for the investigation of the interaction between the nerve and muscle, observing the transmission of signals and studying the response of the muscle to nerve stimulation. Commonly studied muscles and nerves in this context include the gastrocnemius muscle and the sciatic nerve in animal models.
motor nueronsNerve tissue carries electrical signals that affect muscle tissue. Nerve tissue's function is to move and coordinate the way the body functions.
yes in my lower back
Threshod is the amount of force or exertion that a muscle or nerve cell can withstand at the peak of stimulation. Extending over a threshold can lead to cell over-exertion and possible damage to the internal structures.
Damage to the spine can affect the reflex arc by delaying the nerve pathway or making it so you are unable to move a muscle.
Facial nerve
radial nerve
its most likely a trapped nerve. i get this every now and again too and im pretty sure i dont have worms.
Femoral nerve
